This invention .mlates to. a therapeutic .light-radiating appliance of the k:'md provided with means for producing el'ectric induction currents which may either be passed directly through the' human body or be employed for. inducing curre'nts in the same.

The ihvention consists in the combinati0n with a metal cage wherein an eleotric lan1p and an inductior1 coil are enclo sed and wherein the primary of said coil is in series with the lamp, 013 means whereby the secthe elements when the el ctrde of Fig. 2 is attached.

The apparatus has a base composed of a casing 1 which supports an inducti on cil 2 and which is conne'cted by bars 11 120 a ring 11 so as to form a cage. Within this cage an electric lamp 9 is locate. The lamp is mounted in' a holder 8 which is supported on the coil 2 by mean's oi a metal plate 7. A shouldered insulating disc 12 arrangjed within and supported on the ring 11", holds a metal platze 21 between which and 'the platte 7 a semi-cylindrical metal reflectof 22 for the lamp is supported-so as to be in ele'ctric -connection with the' two plafes. The edges of' the plates are raised for the rotention between the Platesofi a cylinder 23 of plain or coloured so 12, which, is held in 'lhe insulating osition on the ring 11 by means of a screw cap 14, supports a screw socket 18 for th e reception of a screw 19 having an insulated head 01 knob 19. About the socket 18 a sleeve 15 is arranged which is slidably guided in the insulating disc 12 and which projec ts beyond th6 top surface of.the latter. A spring 17 supported on the plate 21, bears against a flange 16 on the sleeve 15 and tends to hold said flange against a plat 13 oarriecl by the insulating disc 12. The head of the screw 19 is recessed at 19" so that it can bei screwed o ver the socket'l8 into close contatflil' with the sleeve 15 bat without normall'y deou'red glass c tho plate 11" connected to tho bars 11.

presing-the Same. Hov'vever, when a lug 01 like terminal 20 (Fig. 20) is inserted between t,he head of the screw 19 and theend of the sleeve 15 *and the screw is tightened up, tho sleeve will be dpres'sed so as t0 i nterrupt the contact betWeen the flange 16 und the plate 13. The latter is the ring16 and th1ough the baps11 with the c'asi ng 1, sind the casing is connected at 24 with one pole of the secondarj 2 'of the induction coil2. The other poleof the secondary is corinected .to the plate 7. The p1:i mary 2 series' with the lamp 9 and receives its eur- -rent from a Iead 10.

The induotion coil has an whereby its efliciency. can known rx1anner. is effected by index 5 is. provided whereby any particular lrn core 3 be regulated in The adjustment of the core setting can be repeawd by reference to a f cale 6.

Normally the apparatus is used for lightconnected through of the induction coil is arranged 111- me'ansofa screw 4, und an treatment and the light may be modified by surrounding t he lamp with diiferently C01- y'linders 23. The lamp is fecl with altern1t1ng current which, as 1 t passes through t-he pnrnary of the induction coil, induces a high voltage current in the secondary of the ooil-. Normally the laf-ter is shortcircuited through the cage owing to the Contact of the flange 16 with the plate 13. The current assing through the cage sets' up around e latter an be u tilized for therapeutio purposes. If 1t is desiredto pass the high voltage currents through the body, the terminal 20, which is connected b'y a lead to an electrode 25, is inserted under the screw 19 and olamped in Position. The sleeve 15 is then depressed, and the contact between the flange 16 and the late 13 is interrupted( If now the elec tro e 25 is placed on one part of the body and the casing 1 on anotherpart, the circuit oi the secondary (zoil will be closed through s ring 17 the sleeve 15, the terminal 20, the e ectrode 25, and through the body to which the eleotrode and the casing l have bee'rx appli ed.

The current may be assed in this mann'er througha bar for wh1ch purpose a second electrod and lead, like Fig. 2, may be Con- 7, the refleotor 22, the platze 21, the
